event.target和时间计算实例详解

Vue.filter("time", function(value) {
   var time;
   var minutes = timeErrand(value);
   if(minutes){
      time = minutes+"分钟";
   }else {

      date = now.getDate() >= 10 ? now.getDate() : '0' + now.getDate(),
      hour= now.getHours(),
      minute = now.getMinutes();
   return year + '.' + month + '.' + date; 
}

function timeErrand(value){
    var date1 =  value;  //开始时间
    var date2 = new Date();   //结束时间
